Background

In the present day that petrochemical and coal-fired energy sources are gradually withered, wind power generation or power output has become one of the key directions of human energy development. The data indicate that the total amount of globally exploitable wind energy resources is about many times the total amount of human energy demand. The richness and natural reproducibility of wind energy is the most attractive reason.

Wind power technology has originated in europe, where the development and initiatives for wind power in countries such as denmark, the netherlands, germany have been in history for over 20 years. Since the birth of the wind power generation technology, the wind power generation technology is continuously improved, and the wind turbines which are commonly used at present can be summarized into two types:

1) the vertical axis of the wind wheel of the horizontal axis wind turbine is parallel to the airflow direction. The horizontal axis wind turbine mainly comprises a tower, a horizontal axis wind wheel, a gearbox (an accelerating gearbox), a generator, a wind aligning device, a control system and other components. The wind wheel is used for converting wind energy into mechanical energy, and is formed by mounting blades with good air flow performance on a wheel shaft, and the low-speed rotating wind wheel is accelerated by an accelerating gearbox through a transmission mechanism so as to transmit power to a generator. The horizontal shaft wind turbine has the main advantages that: the wind wheel can be erected at a place higher than the ground, the influence of ground disturbance on the dynamic characteristics of the wind wheel is reduced, the higher the wind wheel is erected from the ground, the larger the wind power is, the higher the generated energy is increased along with the increase of the height, the starting wind speed is low, and the wind wheel can be automatically started. The defects are that the design of the blade profile and the manufacture of the wind wheel are complex; and an additional wind aligning device is needed to adjust the wind aligning direction of the blades of the wind wheel, so that the design difficulty and the cost are increased.

The vertical axis wind turbine is usually arranged in a place close to the ground, and a tower and a wind aligning device are not needed; the vertical shaft wind turbine is driven to rotate by wind, and the generator is driven to rotate by the gearbox. The wind wheel has the advantages that no wind aligning device is needed when the direction of the airflow is changed, and the gyroscopic force of the wind wheel when the wind wheel aligns to the wind is reduced. The structure is relatively simple, and the cost is low. However, the vertical axis wind turbine has a lower wind energy utilization rate than that of the horizontal axis, the wind wheel is greatly influenced by the ground by the airflow close to the ground, and the wind plates of the vertical axis wind turbine are usually fixedly arranged, so that the wind power cannot be received more fully, the conversion efficiency of the wind energy is low, and the actual requirements cannot be met.

The vertical shaft 11 is arranged in the vertical direction and is driven to rotate by a connecting driving assembly. The output of the vertical shaft 11 may drive a generator or other power machine to convert wind energy into kinetic energy for output. The wind plate component is used as a wind receiving piece 13, is pushed by wind to be connected with the driving component to rotate, and comprises a wind plate rolling shaft 12 arranged in parallel with the vertical shaft 11 and the wind receiving piece 13 fixedly combined with the wind plate rolling shaft 12. The wind board assembly may adopt various wind board assemblies of the prior art, such as the windsurfing board assembly disclosed in chinese utility model patent No. 200920133508.3. The windward member 13 of the windboard assembly may be a drag type windboard or a lift type windboard (as shown in fig. 4). Of course, the wind receiving member 13 of the wind plate assembly can also be made of a solar cell panel, so that the wind plate assembly can be combined with solar energy to generate electricity.

The connection driving assembly, as a power transmission assembly, is connected between the vertical shaft 11 and the wind plate assembly, and may include two sets separately disposed at the upper and lower ends of the vertical shaft 11, and one of the sets is described below as an example. The axis of the connecting driving component is fixedly connected with the vertical shaft 11, and the outer end of the connecting driving component is connected with the wind plate component.

In this embodiment, the connecting driving assembly includes a plurality of driving links 14 respectively disposed at upper and lower ends of the vertical shaft 11. The number of the driving connecting rods 14 corresponds to that of the wind plate assemblies, the inner ends of the driving connecting rods 14 are fixedly connected with the vertical shaft 11, and the outer ends of the driving connecting rods are connected with the wind plate assemblies. The outer end of the driving connecting rod 14 is provided with a connecting hole 15, and the wind plate rollers 12 on the upper side and the lower side of the wind plate assembly can be rotatably inserted into the corresponding connecting holes 15 of the driving connecting rod 14 on the upper side and the lower side, so that the wind plate assembly can push the driving connecting rod 14 to rotate, and can also rotate around the wind plate rollers 12.

It is understood that the periphery of the flap rollers 12 may be provided with bearings or the like to reduce friction between the flap rollers 12 and the connecting holes 15 of the driving link 14.

In order to keep the wind plate assembly at a reasonable wind facing position all the time during the rotation process, the eccentric ring type wind power mechanism is also provided with a movable circular ring 16 which can translate in the horizontal direction. In this embodiment, the movable rings 16 are disposed on both upper and lower sides of the wind plate assembly, respectively, but only one of them may be disposed as required.

Each movable ring 16 is provided with a guide groove 17; correspondingly, an inner plate roller 18 is provided at an end of an inner plate of the damper assembly, and the inner plate roller 18 is rotatably inserted into the guide groove 17. It is understood that a bearing may be further provided on the outer periphery of the inner plate roller 18 to reduce friction between the inner plate roller 18 and the guide groove 17.

In the present embodiment, the damper assembly is divided into an inner plate on the side close to the vertical shaft 11 and an outer plate on the side far from the vertical shaft 11, with the position of the driving assembly (i.e., the line connecting the damper rollers 12 on the upper and lower sides) as a boundary; moreover, the area of the outer plate is larger than that of the inner plate, so that the wind area of the outer plate is always larger than that of the inner plate, and resultant force for pushing the movable ring 16 to reach a proper position and pushing the connecting driving assembly to rotate is formed.

When the air plate assemblies are subjected to wind, each air plate assembly gives pressure to the movable circular ring 16, the larger the opening of the air plate assembly gives the pressure to the movable circular ring 16 is, and the resultant force of the pressure given by the air plate assembly to the movable circular ring 16 determines the position of the movable circular ring 16. When the wind plate assembly rotates around the vertical shaft 11, the inner plate rolling shaft 18 is inserted into the guide groove 17 and is guided by the guide groove 17, so that the wind receiving angle of the wind plate assembly is changed, the wind plate assembly is always kept at the most reasonable wind receiving position, and the utilization efficiency of wind energy is improved.

Moreover, the outer fixed ring 20 and the movable ring 16 are in the same horizontal position, so that the movable ring 16 can only horizontally move in the outer fixed ring 20, and the function of limiting the movable ring 16 is achieved.

To prevent the aerofoil assembly from being blown over, the width of the inner plate plus the length of the diameter of the mobile ring 16 is greater than the diameter of the outer fixed ring 20. Or the width of the inner plate plus the diameter of the movable ring 16 is equal to the diameter of the outer fixed ring 20, and at this time, a plurality of partitions are arranged in the movable ring 16, the partitions have the same size, and the number of the partitions is equal to the number of the wind plates.

Furthermore, the total length of the cambered surfaces of the wind plate components is designed to be larger than or equal to the perimeter of the outer fixed rings 20, so that the wind plate components can be sequentially arranged between the upper outer fixed ring 20 and the lower outer fixed ring 20 when not rotating, the inner plate rolling shafts 18 can be separated from the guide grooves 1 of the movable rings 16 and are connected end to form a cylinder, and thus, when the wind speed is too high, the wind turbine is prevented from being damaged.
